Just to give you a heads up, that tech article should not be in there.
I'm going to point out some things, and I'm going to suggest higher-quality and easier to use wire strippers:
Things wrong with that post:
-Never EVER tap onto the starting solenoid.
Buy something like this for your battery terminal.
That way, you solder/braze a ring terminal onto your main power wire, and accessory fuse block power wire, and they are kept neat, and you can ensure a proper connection.
-Don't make your own inline fuses like that. It looks like shit, and it's a pain in the ass. Get a fuse block, or a proper inline fuse.
-Don't use those quick-splice connecters, because there shouldn't be anything that you need to splice into. IF on the rare chance you do need to, the best thing to do, and this can be done with the strippers I posted, is to splice the wire open, get some shrink wrap on there, solder it, and shrink tube it.
You're well on the right track when it comes to buying a proper fuse block, but please, for our sake, and mainly yours, do a job. Don't half-ass it
